This study is a quasi
experimental research involving 35 students in the experimental group (taught
probability concepts using CD-ROM) and eight students in the control group
(taught same topics using the traditional method of teaching). The experimental
group were sophomore students taking up Information Technology while the control
group were mixture of different courses. The statistical tools used were the t
test of the difference of means for dependent and independent correlated
samples, descriptive statistics, and the regression analysis using spss 11.5
version. The following were the findings of the study. There is a significant
difference between the mean of the achievement test of the pretest and the mean
of the achievement test of the posttest in the experimental group. There is no
significant difference between the mean of the pretest and the mean of the
posttest of the achievement tests in the control group. There is no significant
difference between the pretests of both the experimental and the control group.
There is a significant difference between the posttests of the experimental and
the control groups. The variables that are correlated significantly at the .05
level of significance are: high school mathematics grade and the college
entrance test total; the high school general weighted average with the college
entrance test total. The posttest is not correlated with any of the variables
and neither is the pretest correlated with any of the variables. The predictors
of the posttest achievement test are the pretest achievement, the high school
mathematics grade, the high school general weighted average, the college
entrance test in mathematics, the college entrance test total score.
